Gas GENERATOR.

Application filed .Tuly 18, 1925.

This invention relates to gas generators, and has for an object the provision of a container for fluid and a submerged container for material such as iron sulfid in such relation to t-he first mentioned container' that the fluid in the first mentioned container may have access to the second mentioned con tainer proportional to the requirements and proportinal to the pressure of gas developed through the moistening of the iron sulfid, (to be hereinafter referred to as the charge), as fluid gains access to the said charge.

It is an object of this invention to produce a gas generator in which novel means are provided for maintaining` the apparatus against fouling which might be due to the accumulation of spent charges at t-he bottom of the apparatus.

itis furthermore an Yobject of this invention to provide novel means for preventing the development of excessive pressure within the apparatus.

It is a further object of the invention to V provide means for so regulating the pressure as to prevent injury to parts of the apparatus or to objects exterior of the apparatus, through the employment of an equalizer by which the generation of gas is controlled.

It is a still further object of this invention to produce a generator of the character indicated, the parts of which can be readily assembled or dismantled and in which the charge can be expeditiouslyrenewed.

l/Vith the foregoing and other objects in view, the invention consists in the details of construction, andin the arrangement and combination of parts to be hereinafter more fully set Jforth and claimed.

1n describing the invention in'detail, reference will be had tothe accompanying drawings forming part of this application wherein like characters denote corresponding parts in the several views, and in which- Figure 1 illustrates a sectional view of a generator embodying the invention;

Figure 2 illustrates a` sectional view of the device on the line 2 2 of Fig. 1 with the charge omitted; and

Figure 3 illustrates a sectional view on the line 3-3 of Fig. 1.

In these drawings, 5 denotes a tank or container which is rather high and narrow, the r said container having a lid 6 and a drain cock 7, the latter being located at the bottom Serial No. 44,553.

of the container and effective to permit the withdrawal of the spent acid or sludge in order that the device may be freed of such acids and the container may be maintained in a highly efficient state of operation.

The pipe S is located vertically in the container and extends eXteriorly thereof at the top where it is provided with any suitable service pipe 9 that may lead to a source of consumption. The pipe 8 hasa gooseneck or loop 10 at the bottom of the container and the inner end of the pipe is located a suitable distance above the bottom of the container.

A charge receiving jar or holder 1.1 when in operative relation to the container is'bellshaped and preferably it has a handle 12 at its top to facilitate its application to and removal from the container. of' the wall of the said holder 11 there is a curved partition or wall 13 integral withV or so connected to the holder as to produce a tight joint. The curved partition with the wall of the holder forms a chamber in which the upward extension of the pipe 8 is located, and the said pipe terminates below the upper end of the said partition.

rl`he partition has a port or opening 1lat its upper end which permits gas to pass from the holder to the said chamber and to and into the pipe where under pressure it is forced to the service pipe 9.

The interior wall of the bell or holder` is further provided with segmental flanges 15 and 16 that extend inwardly and form supports or shelves for the bottom 17 of the holder, which bottom is perforated to permit fluid to pass into the holder in order that it will gain access to the charge 18 within the holder, and the said apertures further permit the escape of spent acid or sludge which may gravitate to the bottom and be dis` charged, as heretofore indicated. The -bottom 17 is so shaped that it will clear the edges of the flanges 15 and 16 when inserted, and when turned, will'be supported by the said flanges. i

The holder is supported in the container clear of the bottom thereof by a suitable base 19 of appropriate construction, and the in; ventor does not wish to be limited with respect to the particular form of the base.

1n carrying the invention into practice, the holder is filled with a charge of solid material such as FeS, CaCO3 or the like and the bottom or plate 17 is inserted and held On the interior in place by the interengaging parts heretofore described, and the said holder is then placed in the container. The fluid which is in the nature of an acid is then added to the container and if the pipe 8 is opened, gasY the gas will be generated`Y more` speedily up to the 4capacity of. the generator. i It; the passage of gas through the pipe isinteirupted, the gas being generated 1s unableto escape from the-.jarI and its. pressurek Jforces the acid. out of. the holder throughl the plate or bottom 17,.` The acid which coats the charge,andwhichzremains afterthe acid has been forced' out of the holder is quickly spent, and a small` reserve chamber is provided below the plate asa. storage for the gas generatedby the residual acid, it being shown tliatthe plate 17ers located adistanc'e above the lower edge Otv the holder.

In casethe generator is subjected toy a gas pressure beyond itscapacity,- as when a connection4 is accidentally broken, the acid rises in the holder until the outlet pipe is submerged and the line at once ills to` the level ot the acid in the'container but not higher, as thesyStein is then in equilibrium. The arrangement of parts,'therefore, automatically controls the operation of the generator and interrupts the development' of gas or pressure, and the apparatus can only be restoredl toV operative conditionby blowing the pipe clear ofy iiuidito'perinit gas to again low. The provision for interrupting the functioning ofthe gas generator is ot importance when the device -is used for the productionof poisonous gases as a room or compartment cannot beV accidentally flooded with the gas. l

It will be seen from an inspection of the drawing and from the toregoing description that the apparatus is a compact structure and that the pressure can be regulated by varying the height of the liquid in. the container. The. capacity ot the holder is'sucli and the arrangement for filling the saidholder as of the column of liq-v provided permits the use of relativelyl large pieces `ofsolid'material intheholder, and the said holder can be filled and emptied expeditiously. The device is constructed without connections that-.are liable to become weak and produce leaks and the construction is such that there are no restricted passages to become fouledor choked.

I claim:` Y 1.*Inay gas generator, a liquid container, a bell-shaped charge holder thereimlnieanszfor supporting the charge holder above the bolttoml ofl the container, a perforated bottom for the charge holder, meaiisfor holding the bottom in the charge holder above the lower edge ofthe charge holder, a verticalpartition inthe holder', thel said partitionliaving a port iny its upper end'j communicating with the charge area of theholder, aI pipe standing in the container andhaving ay discharge end located above the liquidi in the. container, the said pipe having a gooseneck portion extending upwardly into the lspace between tlieinner wallofftlie 'holder and the said partition whereby gas generated i'ntlie holderV escapes through the, said pipe.

Q. In a gas generator,a liquid containena bell-shaped charge holder therein, segmental flanges extending; inwardlyy 'fromV the' inner wallv ot the holder, a bottom litt'ed to the iiiterior of the holder 'and supported on the flanges, the said bottoni being arranged to permit fluid to enter the holder iroin the container, a vertical partition in the holder, the ysai'dpartition having a port in its upper end communicating with the charge area, or' the holder, a pipe standing. in the container and having a discharge endlocated above the liquid inthe container, the said pipe having. a gooseneck'portion extending upwardly into the space between, the inner wall of vthe holder and the saidl partition whereby gas generated 'in the holder escapes through the saidpipe.

3. In a gas generator, av liquid container, a bell-shaped charge. holder supported therein near the bottom, means for supporting a charge 'in the charge holder, a pipe extending vertically in the liquid container and having a gooseneck portion projecting upwardly into the charger holder for receiving gas from a location near the ltop of' the charge holder.
